. noon COVERING.

Application filed May 15,

To all whom it may concern:

Be it known that I, HENRY R. WARDELL,' a citizen of the United States ofAmerica, residing at New York city, in the county and State of New York,have invented certain new and useful Improvements in Roof Coverings, ofwhich the following is a specification. 1

My invention relates to roof coverings in general and more specificallycomprises a form of shingle-strip of waterproof material for use inproducing a waterproof covering which shall simulate an ordinaryshingled roof. a

One embodiment of the preferredforin of my invention is illustrated'inthe accompanying sheet of drawings in which:

Fig. .1, is a plan View of my improved shingle strip, and

Fig. 2, is a plan view of a portion of a roof with my invention appliedthereto, parts being broken away.

Throughout the drawings likereference characters indicate like parts: 1,indicates a. strip of waterproof fabric which may be asbestos felt, ragfelt or any other fibrous felt or similar material heavily saturated orimpregnated with a hydrocarbon, such as asphalt or other suitablewaterproof com pound, which is preferably dark in color and forms anadhesive surface on the material, at least when hot.' This strip has awidth approximating the length of a standard shingle, say ten inches,and a length equal to the combined widths of a predetermined pluralityof standard shingles plus that of a similar number of narrowinterspaces, each, for instance, one-half inch in width.v- Preferablythe strip should have a length of about 32 inches and take the place offour separate shingles as shown. 2, 2, represent a plurality ofdelimited sections of the surface area of each strip 1, each said spaceconforming to the outline of a standard shingle, which sections extendacross the strip, and throughout each of which alayer of crushed mineralmaterial, such as slate or serpentine rock of lighter color, contrastingwith that of the saturated fabric, is embedded in the adhesive surfaceof the fabric. This may be applied and'rolled in while the surface ishot. These areas, 2, 2, are separated by narrow spaces, 3, 3, each, forinstance, one-half inch in width, where the surface of the saturatedfabric is left 1922. Serial no 5si,155.

bare and exposed without any mineral layer superposed thereon. Thesealternate coveredand exposed areas extendacross the strip ,1 as shown. 1I

Preferablyeach end of each strip of fabric 1 has its saturated surfacealso exposed and free from mineral covering as shown at 4, 4, for adistance equal to half the width of the intermediate exposed spacesv3,3, say each one-quarter inch wide so that when the ends of adjacentstrips 1, 1, are abutted the markings will be uniform throughout theroof.

Preferably also each strip 1 a plu rality of V-shaped notches 5, 5,along one of its longer edges and 'an-oppositely disposed plurality ofsimilar V-shaped tabs 6, 6, along the other longer edge, the apices ofthe Vs registering with the ends of the exposed narrow spaces 3, 3. Twoof the corners of the strips ,1, 1, are clipped at 7 7 to form half Vsand the other corners are provided with half tabs- 8, 8,-to produce auniform effect when the ends of adjacent strips are abutted to cover-aroof. In applylng my invention to a roofflsuc ce'ssive series ofabutting strips 1 1, are

overlapped, as shown in Fig. 2, to simulate the usual appearance of ashingle roof.

The advantages of my invention comprise a reduction of the usualtendency to curl at the edges developed in the use of ordinary sO-calledasphalt shingles, and in the reductionof Open spaces between shingles,up

through which rain may be driven' by a strong .wind.

The exposed spaces 3, and 4, may be formed by scrapingoif'the layer ofmineral covering from thecompletely covered strip,

or, before applying the mineral layer, paper ribbons may be laid overthe adhesive surface so that the mineral material will not adhere atthose parts when being sprinkled over the fabric 1.

Having described my invention, I claim:

As a new article of manufacture a shingle strip having a widthapproximately equal to the length of standard shingles and a lengthequal to the combined widths of a. predetermined plurality of standardshingles plus that of a similar number of narrow interspaces, saidstrips being composed of a suitable fabric saturated with a waterproofcompound of a dark color and adhesive character and having crushedmineral par was ticles embedded in the adhesive surface so equallyspaced apart and extending across the strips, and the narrow,intervening spaces of the bare surface of the saturated fabricof darkercolor, being exposed and devoid of mineral covering betweenthe-continuous areas so delimited, said shingle strip 10 having aplurality of ll-shaped notches along one of the longer edges and anoppositely disposed plurality of similar V- shaped tabs along the otherlonger edge, the apices of the Vs registering with the 15 ends of theexposed narrow spaces.

HENRY R. WARDELL.
